I have been using a fully functional pre for almost a week now. Call quality is excellent on both sides though I have to say battery is not what I would like. It has a hard time making it through a day of heavy use like I and what im assuming most people who get it will use it. The OS is the best Ive used and I have an Ipod Touch, a touch pro, and have used the G1. The screen is amazing too, far better picture than the iPhone due to its 24-bit display. video playback is smooth crisp and clear and the audio quality is also impressive, especially over bluetooth. The keys on the keyboard seem small at first but are very easy to get used to. The slider does bother me though as its tough to slide out and as of yet there is no OSK. The OS at first seems to be missing several vital apps such as weather but these can already be found for free on the app catalog. Once I have more time I can write a full review for anyone that wants one.
